Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 173,227,439, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 173,227,439 | |
| -1 | -173,227,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,227,439.
Example:
1 x 173,227,439 = 173,227,439
and
-1 x -173,227,439 = 173,227,439
Notice both answers equal 173,227,439
With that explanation out of the way, let's continue. Next, we take the number 173,227,439 and divide it by 2:
173,227,439 ÷ 2 = 86,613,719.5
If the quotient is a whole number, then 2 and 86,613,719.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 173,227,439 | |
| -1 | -173,227,439 |
Now, we try dividing 173,227,439 by 3:
173,227,439 ÷ 3 = 57,742,479.6667
If the quotient is a whole number, then 3 and 57,742,479.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 173,227,439 | |
| -1 | -173,227,439 |
Let's try dividing by 4:
173,227,439 ÷ 4 = 43,306,859.75
If the quotient is a whole number, then 4 and 43,306,859.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 173,227,439 | |
| -1 | 173,227,439 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 239 | 1,673 | 2,629 | 9,413 | 18,403 | 65,891 | 103,543 | 724,801 | 2,249,707 | 15,747,949 | 24,746,777 | 173,227,439 |
| -1 | -7 | -11 | -77 | -239 | -1,673 | -2,629 | -9,413 | -18,403 | -65,891 | -103,543 | -724,801 | -2,249,707 | -15,747,949 | -24,746,777 | -173,227,439 |
